"Then why is the A-B-Sea Serpent like a city?" asked the Rattlesnake promptly.
The Scarecrow thought hard for several seconds.
"Because it is made up of blocks!" he roared triumphantly. "That's easy; now it's my turn. Why is the A-B-Sea Serpent such a slow talker?"
"Give it up!" said the Rattlesnake after shaking himself several times.
"Because his tongue is a tape measure, and he has to measure his words!" cried the Scarecrow, snapping his clumsy fingers. "And that's a good one, if I did make it myself. I must remember to tell it to Dorothy!"
Then he sobered quite suddenly, for the thought of Dorothy brought back the purpose of his journey. Interrupting the Rattlesnake in the midst of a new riddle, he explained how anxious he was to return to the little farm where he had been discovered and try to find some traces of his family.
"And the real riddle," he sighed with a wave of his hand, "is how to cross this river."
"That's easy and no riddle at all," rumbled the A-B-Sea Serpent, who had been listening attentively to the Scarecrow's remarks. "I'll stretch across, and you can walk over." Suiting the action to the word, he began backing very cautiously toward the river so as not to shake the Scarecrow off his feet.
"Mind your P's and Q's!" called the Rattlesnake warningly. It was well that he spoke, for the A-B-Sea Serpent had doubled the P and Q blocks under, and they were ready to snap off. Finally, however, he managed to make a bridge of himself, and the Scarecrow stepped easily over the blocks, the huge serpent holding himself rigid. Just as he reached Y, the unfortunate creature sneezed, and all the blocks rattled together. Up flew the Scarecrow and escaped falling into the stream only by the narrowest margin.
